Finding the equation of a circle given the radius and one point?

It can't be done. There are an infinite number of circles with a specific radius and which go through a specific point. What you need is the centre of the circle.
If you have two points that the circle crosses, then you can narrow it down to two possible circles.
If you have three points that the circle crosses, then you can narrow the list of possible circles down to a single circle.
But without the information above, it's impossible.

What is the equation to get the area of a circle if you have the radius?
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
What is the circumference of a circle if the radius is 4.83cm?
The circumference of a circle is given by the equation C=2*pi*r (r being the circle's radius). So, the circumference you're looking for is 30.35 cm.
How do you find circumference given radius?
2 pi rthis is the equation of the circumference of a circle. just multiply out 2 times pi(3.14159) times the radius that you were given.
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
Was is the equation for the radius given diameter?
The radius of a circle is equal to 1/2 of it's diameter. radius is one half of the diameter. Therefore ; r = (1/2) D
What is the radius of curvature?
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.
If a circle is centered at the origin and the length of its radius is 6 What is the circle's equation?
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.
What is the formula for finding diameter when given the area?
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
If the circumference of a circle is 2053 feet what is the radius of the circle?
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
What is the radius of a circle given an arc and its height?
if you are given the circle's "height" then that is the diameter. the diameter is twice the length of the radius, so divide the height by two and you will get the radius.
